JACKING AND TIRE CHANGING
WARNING!
²Being under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never put any part of your body
under a vehicle that is on a jack. Never start or run
the engine while the vehicle is on a jack. If you need
to get under a raised vehicle, take it to an authorized
service center where it can be raised on a lift.
²The jack is designed to use as a tool for changing
tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should
be jacked on a firm level surface only. Avoid ice or
slippery areas.
Jack Location
The jack and jack tools are stored under the front passenger
seat. Lift the flap on the side of the seat for access.
Removal (2500/3500/Mega Cab)

Tire Changing Procedure
WARNING!
Getting under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never get any part of your body
under a vehicle that is on a jack. Never start or run
the engine while the vehicle is on a jack. If you need
to get under a raised vehicle, take it to an authorized
service center where it can be raised on a lift.
Do not raise this vehicle using a bumper jack. The jack is
designed as a tool for changing tires on this vehicle only.
It is not recommended that the jack be used for service
purposes or to lift more than one wheel at a time.
Preparations
Park the vehicle on a firm level surface, avoiding ice or
slippery areas. Set the parking brake and place the gear
selector in PARK (automatic transmission) or REVERSE
(manual transmission). On four-wheel drive vehicles,
shift the transfer case to the 4L position.
WARNING!
Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid the danger of being hit when
operating the jack or changing the wheel.
²Turn on the Hazard Warning Flasher.

²Block both the front and rear
of the wheel diagonally oppo-
site the jacking position. For
example, if the right front
wheel is being changed, block
the left rear wheel.
²Passengers should not remain in the vehicle when the
vehicle is being jacked.
Instructions
WARNING!
Carefully follow these tire changing warnings to help prevent
personal injury or damage to your vehicle:
²Always park on a firm, level surface as far from the edge of the
roadway as possible before raising the vehicle.
²Block the wheel diagonally opposite the wheel to be raised.
²Set the parking brake firmly and set an automatic transmis-
sion in park; a manual transmission in reverse.
²Never start or run the engine with the vehicle on a jack.
²Do not let anyone sit in the vehicle when it is on a jack.
²Do not get under the vehicle when it is on a jack.
²Only use the jack in the positions indicated and for lifting this
vehicle during a tire change.
²If working on or near a roadway, be extremely careful of motor
traffic.
²To assure that spare tires, flat or inflated are securely stowed,
spares must be stowed with the valve stem facing the ground.
²Turn on the Hazard warning flasher.

5. Connect the other cable; first to the negative terminal
of the booster battery, and then to the engine of the
vehicle with the discharged battery. Make sure you have
a good contact on the engine.
WARNING!
²You should not try to start your vehicle by pushing
or towing.
²Do not connect the cable to the negative post of the
discharge battery. The resulting electrical spark
could cause the battery to explode.
²During cold weather when temperatures are be-
low freezing point, electrolyte in a discharged
battery may freeze. Do not attempt jump-starting
because the battery could rupture or explode. The
battery temperature must be brought up above
freezing point before attempting jump-start.
6. Start the engine in the vehicle which has the booster
battery, let the engine idle a few minutes, then start the
engine in the vehicle with the discharged battery.
436 WHAT TO DO IN EMERGENCIES

7. When removing the jumper cables, reverse the above
sequence exactly. Be careful of the moving belts and fan.
WARNING!
Any procedure other than above could result in:
1. Personal injury caused by electrolyte squirting out
the battery vent;
2. Personal injury or property damage due to battery
explosion;
3. Damage to charging system of booster vehicle or
of immobilized vehicle.
FREEING A STUCK VEHICLE
If the vehicle becomes stuck in snow, sand, or mud, it can
often be moved by a rocking motion. Move the gear
selector rhythmically between DRIVE and REVERSE
(automatic transmissions) or between 1st and REVERSE
(manual transmissions), while applying slight pressure to
the accelerator.
In general, the least amount of accelerator pedal pressure
to maintain the rocking motion without spinning the
wheels or racing the engine, is most effective. Racing the
engine or spinning the wheels, due to the frustration of
not freeing the vehicle, may lead to transmission over-
heating and failure. Allow the engine to idle with the
transmission selector in NEUTRAL for at least one
minute after every five rocking-motion cycles. This will
minimize overheating and reduce the risk of transmis-
sion failure during prolonged efforts to free a stuck
vehicle.
